HENRY D. SMITH, OF BROWNSBORO, TEXAS.

WRENCH.

To all whom it may concern:

Be it known that I, HENRY D. SMITH, a citizen of the United. States,residing at Brownsboro, in the county of Henderson and State of Texas,have invented certain new and useful Improvements in Wrenches, of whichthe following is a specification.

This invention relates to wrenches, and primarily to that type which isadapted to be associated with other tools. Due to the construction ofthe wrench, a screw driver may be provided on a movable part thereofwhereby the device will be of a most desirable nature.

A further object of this invention is to provide a wrench which may bequickly and easily adjusted and also to provide a device which may beoperated so as to retain the jaws of the wrench in fixed positions.

For a full understanding of the invention reference is to be had to thefollowing detail description and the accompanying drawings, in whichFigure 1 is a side elevation disclosing the present invention; Fig. 2 isa front elevation; Fig. 3 is a View illustrating a detail used in theconstruction of the present invention.

Referring more particularly to the drawings 1 indicates the main shankof the wrench having jaws 2 and 2 extending laterally at one terminal,the shank being provided with a. slot 3 as illustrated. Slidably mountedwithin the slot 3 is a aw t having a shank 5 provided with a toothedportion and adapted to operate within said slot. The jaw 4 may have anextension 4 thus forming two wrenches, one of which may be provided withteeth to form a pipe wrench as illustrated. A plate 6 may be secured tothe main shank for retaining the shank 5 within the slot.

Pivotally mounted to the main shank within the slot is a toothed member7 said toothed member being adapted to engage the toothed portion of theshank 5 for retaining the wrench at any predetermined adjustment. Thefree end of the member '7 is drawn out as at 8 so as to be used as ascrew driver. A catch 9 is secured to the main shank and adapted toengage the member 7 for retaining the latter closed or within the slot3.

A die plate 10 is detachably retained in the slot 3 by set screws 11thus making it possible to change the die plate to the styleSpecification of Letters Patent.

needed. In the bifurcated portion of the handle is rotatably mounted aratchet 12 which is held in rigid relation to the handle or main shankby a spring actuated pawl 18. The ratchet 12 is provided with an opening14 in which may be inserted a socket 15 as illustrated, using the sameas a ratchet wrench or drill or countersink, the drill 0r countersink tobe carried by the socket as shown at 16 in Fig. 2.

Rotatably mounted on the main shank is a safety catch or member 17provided with a recess 18 said recess being of suflicient depth topermit the toothed portion of the shank 5 to pass without engagementwith the catch or lock 17. The toothed portion of the shank 5 is formedwith semi-circular recesses between the teeth, said recesses permittingthe member 17 which is circular in cross section to be turned intoengagement with the shank 5. A. deepened recess 19 is provided in thepivoted member 7 to receive the safety look.

In operation, for using the wrench at random for different size nuts thelock 17 is turned to the position as illustrated in Figs. 1 and 2, thepivoted member forming a sufficient means for retaining the jaws attemporary adjustments. For using the wrench constantly on nuts of thesame size the lock 17 is turned half way around thus bringing the sameinto engagement with the toothed portion of the shank 5, rigidlyretaining the same and preventing the slipping of the jaws.

Having thus described my invention, what is claimed as new is:

1. In a wrench, a main shank provided with a slot and having a jaw atone terminal, a jaw slidably mounted in said slotted portion and havinga shank provided with a toothed portion, a member pivotally mounted onsaid main shank and provided with a toothed portion adapted to engagethe toothed portion of said shank, and a member rotatably mounted insaid handle adapted to retain said slidable jaw in fixed relation to themain shank, for the purposes herein set forth.

2. In a wrench, a main shank provided with a slot and having a jaw atone terminal, a slidable jaw mounted in said slotted portion and havinga shank provided with a toothed portion, a member pivotally mounted insaid slot and provided with a toothed portion adapted to engage thetoothed portion of said shank and a member provided with a recess, saidmember being rotatablv mounted in said handle and adapted to be rotatedinto and out of engagement with the toothed portion of the shank of saidslidable jaw, for the purposes herein set forth.

3. In a wrench, a main shank provided with a slot and having a jaw atone terminal, a slidable jaw mounted in said slotted portion and havinga shank provided with a toothed portion, a member pivoted in said slotand provided with an approxi-
